a1df06b363 This has been added to avoid the situation where some host ctype.h functions
return true for characters > 127.  I.e. they are allowing extended ASCII
characters through which then cause problems.  E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably.  Likewise letters with diacritical marks can also cause problems.

If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.

The implementation uses a single table with a bit for each of the defined
classes.  These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set.  They will
work for both signed and unsigned character inputs.

cf37aaa335 Consolidate to a single asn1_time_from_tm() function
Add missing ASN1_TIME functions

Do some cleanup of the ASN1_TIME code.
Add ASN1_TIME_normalize() to normalize ASN1_TIME structures.
Add ASN1_TIME_compare() to compare two ASN1_TIME structures.
Add ASN1_TIME_cmp_time_t() to compare an ASN1_TIME to time_t
(generic version of ASN1_UTCTIME_cmp_time_t()).

Replace '0' .. '9' compares with isdigit()

b7e011f8b6 asn1/a_time.c: make handling of 'fractional point' formally correct.
Even though tm->length >= 15 && v[14] == '.' works in practice,
[because "YYYYMMDDHHMMSS." would be rejected as invalid by
asn1_time_to_tm,] formal correctness with respect to buffer
overstep in few lines vicinity improves readability.

[Also fold one if condition and improve expression readability.]

f673c4f8f2 Refactor ASN1_TIME_print functions
Check time string format before parsing
Reduce more duplicated code
By involving asn1_time_to_tm, we can now get information we mostly need
to print a time string.

This follows what was discussed at

3d0f1cb9fd Add asn1_time_to_tm function and check days in month
Based on discussion in PR #3566. Reduce duplicated code in original
asn1_utctime_to_tm and asn1_generalizedtime_to_tm, and introduce a new
internal function asn1_time_to_tm. This function also checks if the days
in the input time string is valid or not for the corresponding month.

Test cases are also added.

Also fix the undefined behaviour `*(long *)x = y` when x isn't a long or character pointer.

Make funcs to deal with non-null-term'd string
in both asn1_generalizedtime_to_tm() and asn1_utctime_to_tm().

Fixes issue #3444.

This one is used to enforce strict format (RFC 5280) check and to
convert GeneralizedTime to UTCTime.

apps/ca has been changed to use the new API.

Test cases and documentation are updated/added
